Hi @TeriSerugi,
I’m sorry about your experience.
Usually, this kind is solved by adjusting your network and/or browser configuration:
- Are you blocking WebSocket connections -
wsandwss- The IDE, Simulation, and terminals need these to work. - Are you using an ad block software? If so, you may have to temporarily disable this or whitelist
*.theconstructsim.comand*.robotigniteacademy.com. - Are third party cookies enabled?
- Is JavaScript enabled?
About the error shown in the notebook window, can you share a screenshot? Also, please copy paste the messages you see in your browser console here - it might give us some hints.
For further hints, please also check the post below:
